    May 13, 2019 · The closed-side setting of a jaw crusher helps determine the nip angle within a chamber, typically 19 to 23 degrees. Too large of an angle causes boiling in the crushing chamber. This is where the jaw plates cannot grip onto the rock, and it keeps slipping up and down, avoiding being crushed. The nip angle gets flatter as the machine is set tighter

    The maximum nip angle of the crusher machine is determined by the friction coefficient between the crushing material and the crushing working face. The friction angle of ore to steel plate is generally 17 degrees, so the nip angle should not be greater than 34 degrees. In the actual production, the nip angle of the crusher machine is far less than the limit value. 7. Revolution of the crusher machine. For jaw …
